Rust proofing recommendations?

Does the crown help aluminum?

It prevents corrosion generally so I suspect it would do the same for aluminum

How many spray cans does it typically take to coat the underside of 1 truck?

Sounds like lots of products work pretty darn well.

If you are looking for the best longest lasting DIY with a rattle can, you should check out Cosmoline. There is nothing better for longevity.

I usually go through about 3 cans to do the frame and cross members. I’m sure I could do it with less but I go over a lot of it with lots over overlap. I’ve not tried the cosmoline but I agree the Krown is light weight. This helps with creeping but it will come off sooner too ?‍. By spring not much remains on the rear axle but the frame stays good. Changing out my winters this spring the rails were still tacky and inside the rails were still wet with oil.

I still haven't figured out which one I want to use but a decision has to be made by mid fall. I created a thread which I will attach it here but I am leaning toward either Corrosion Free or Fluid Film. I am afraid of Krown because once I took my Range Rover to them and specifically asked them that I don't want any holes drilled but the car came back with multiple holes and some in high foot traffic areas. Yes, they don't have to drill holes if you tell them but because they are inherently wired to drill every car, they have a tendency to forget relaying that message to the applicator.

Valugard 160. Line x applied it to my truck.
I researched this and think it’s one of the best corrosion applications on the market.

That specific material, VG 160, is the closest thing I have found out there to Cosmoline. Not all LineX shops use it, and some use some other Valugard (VG) but you want the VG 160. Find a good LineX shop with a long 360 degree spraying nozzle for the inner frame, and you will be good to go. Not a cheap date but outstanding long term protection. Even for Canada winters.

So living in the Toronto area, we get a LOT or road salt used in the winter. I am the kind of guy that keeps my vehicles as long as they are not starting to cost too much in repairs. I hope to get 10 years out of my 2024 F150. I have watched the many YouTube videos and reviews of the various undercoating sprays, and I think I will go with the Fluidfilm option. I plan to get them to just spray the frame and undercarriage areas, and not inside the doors. The bodies of these things seem to not need any special treatment since it’s aluminum and I don’t want the spray creep and dirt that comes out of the bottoms of doors. I also have an interlock stone driveway so I don’t want anything to drip. I also don’t want a lot of smell, but I understand that the lanolin sprays do have a bit of funk to them for a while.

I was hoping for some real experienced advice from the F150 crowd on this plan. What are the collective thoughts on rustproof options and recommendations?

Krown rust proofing. I've been using them for years on my other vehicles; never let me down.

I am also looking into LineX. They call it a lifetime application. With yearly touchups I guess

If you call around ask them what they use. If they say Valugard that is not good enough. The very best is Valugard VG 160. If they sound confused ask them to look at the drum and tell you specifically what the full name is.

There are a number of threads here where the members had to search around to find a LineX with this specific product.

Just called them and they said it is VG 104

I’m planning on having it commercially sprayed the first time to make sure it’s deep inside frame rails and cavities, then DIY in future. It seems like there are shops that use Fluidfilm but none that spray Surface Shield. Krown shops are everywhere. But I don’t like the drips with it on the interlock driveway. I used it at my last house and it stained the driveway permanently where it dripped.
